Even worse, GeoIP doesn't even have high enough resolution. I'm currently in Switzerland. Different regions speak German, French and Italian (among others). If you just use "this IP is in Switzerland" to try and guess the best language, you will definitely get it wrong. 25% of .ch pages I have never visited before start out in French, most others in German. No rhyme or reason.
